The

easing l is adage d so be dispesed at one side 0:5 the internal oembustien engine, and as illustrated ispartieuiariy adapted for zippiieetion to a Ford engine, although the preseni device may be altered in its proportions and details, Within the scope of the apyended ciaims' to adapt the manifold to 16 other automobile and kindred engines.

The casing 1 15 provided with a longieudi- 112d partition 2 extending from end to end,

'between the. sideswhereof and providing a relatively narrow intake chamber 3 at ens #5 side, and a relatively wide exhaust chainoer 4 as theiotner or egpesite side.

One end of the casing 1 is formed with an sublet nipple or nozzie 6 cemmunicating vith the corresponding end of .the exhaust or dischargeeiiember', end having si'imion or socket nut 6 threaded. thereon for attack? ing the end. of the exhaust pipe 6* thereto order time the exhaust mey pess from the chamber throughihe pipe 6* into the armies es 'phere, as usual.

The intake oriiiiet chamber 3 is disposed adjacent'the'euter side '7 of ihe casing 1, and the ouier side 7 of the casing and bottom' thereof is provided with :1 depending tilbiiis im" inlet arm 8, the lewer or free end of VilhiCh is formed iii any suitable-Jeanna, as at 9,1?01 the attachment of tiieearbiireter 1 thereto, so that the gaseous apor or earbureted air may fio Tv 5mm the cnrbureeer $55 mirougii the inlet arm 8 to the intake chem her 3, 'The iiiie't arm '8 is disposed intermedieie or HIiCiTYflY between the ends of the casing l to introduce iii: vapor into the intake chamber midway between its ends.

The inner side or back: lleftiie'easing 1 adjacent which the exhaust eim nber i is arranged, is provided at siiitably spaced iongitudinai points with inietopenings 12 soarranged as to slim or register with the 3% exhaust ports of] the engiz epyiinders. As illustrated, four of the iniet openings, 12 for the chamber 4 are provided, fer a'feur-c v1 index engine, it being uedersiood ii st the number of openings lgmeybe ii cre'asedordecreased according to' the circumstances. Copper or similar nipples 13 are preferably engaged \vithin the openings 12 for the reeeptlon of washers orgaskets thereon between the casing 1 and the engine cylinders, I

to provide a tight or non-leaking joint.

Tubular portions 11 are provided between the partition 2 andtinne-r side or wall 11 of the casing to provide outlet openings for the chamber 3, which extend through the chamber} to communicate vith the inlet ports of the engine As illustrated, a pail-of tubular vportions 1e are provided, between the two pairs of openings;12, each of the tubular port ons or outlets for the chamber 3 being adapted to communicate with the respective pairs of engine cylinders to supply the carbureted air, thereto.

inner sides of the casing 1 and through the partition 2, intermediate the openings 12 and tubularportions 14, to provide bores through the'casing and closed oil-from the chamber through the casing and closed oflf from the chambers 3 and "i, through which bores securing bolts or elements 17 may be engaged to engage the body or cylinders of the engine forclamp ing the casin'g'l against the sidethereof, as suggested in Fig. 1;

Baflle partitions 18 are provided between the partition 2 and the outer side or wall- 7 of the casing withinthe chamber 3, so as to extend from the ppposite sides of the-inlet arm 8, over and beyond the tubular portions or outlets 14 of the chamber 3 vvhich extend through the chamber 51- to the inner side of the casing, thebaflies or partitions 18 extending around. the, tubular portions 14' toward the ends of the. casing and preferto.

ably being integral with the tubular portipns Thus the inlet of the chamber 3 thje'chamber 3 between and at ends, of the said bafiles or partitions, and whichwill cause the ind-owing ases or vapor to first pass upwardly andlpngitudinally over the bailies' or part tions and thence around the remote ends of the bafiies and thence under the bafiies to the outlets 14.

In this manner, a thorough circulation and agitation of the vapor or gaseous fuel is provided rior to the-admission of the vapor intojiie cylinders, and whereby the vaor will be properly heated by its contact lith the partition-2 dividing the-chambers 3and4. J

A lurality of pins or'portions 19 are disbetween and integral with the part1- 1 tion 2 and outer side 7 of; the casin throughout the extent of the 'chamber 3, or faclh-v .hting the heating of the vapor.

c Ripples 20 are preferably engageduithin Tubularpo'rtions 16- are .also provided between the outer and I H theipartitions 18, while the .tubular portions or outlets 14 of the said chamber are disposed at the opposite sides of the batlles or partitions 18' between the theinner ends of the tubularmansion openings 14, for the reception 0 gaskets r washers thereon' for providing a tight 'oint between the casing 1 and the-cng1ne only or cylinders. Y

In practice, the presentma'nifold maybe readily attached to the body or cylinders of v the engine, to bring the openings 12 intocommunication with the exhaust ports of the cyl'1nders,and' to bring the openings or.

outlets-1iinto-communication with the inf take portsof the cylinders. Then, the exhaust gases ma '1 be discharged through the openings 12 fro n the ports of the cylinders;- I

into the exhaust chamber 4 of the manifiold,

ilhe present manifold is simple and cor p'actjn construction, so, as not to be cumber-- some, and may be inexpensively manufactured, all of the parts being readilycast integral with the exception of the nipples 'and'20, bolts 17 and nut 6.

The other advantages and capabilities of the present invention will be obvious to those versed in the art withoutfurther comment being deemed necessary. 7

What is claimed is:--- 1. A'combined intake and exhaust mani fold coniprising'a casin having a partition therein forming an intaie dumber between the partition and outer-side of the casing, and

an exhaust chmnber between the part1t ion- I and inner side of the casing, the casing having an inlet and outlet communicatin with the intake and exhanst chambers, respectively, the inner side of'the casing havin o enings communicating with the exhau camber and providing inlets therefor, there being tubular portions between the said artition and inner side of the casing provi 111g outlet openings for the intake chamber extend-- ing throu h the exhaust chamber, and there being but e partitions within the intake chamber between the said artitlon" and outer sidt of the casing, the I rs't mentioned ranged at opposite sides of the baflie'partitions.

2. -A combined intake and exhaust manifold comprising an elongated casing having a longitudinal partition therein. forming an intake chamber between the partition and the outer side of-the casing, and an exhaust inlet and the said tubular portions being anchamberbetween the patrtition and inner-1&0
